ive read stuff that says i will need to get a 50oz fluid dampner to go along with the c4
but then again i read that my flywheel wouldnt bolt up, but mine did. so im curious if i will need to buy a different harmonic balancer and if i should run the stock flywheel?
thanks

i have the same problem well mine is still in the works but i'm planning ahead and i have read that the harmonic balencer will need to get changed but my engine should have a 50 oz weight it's a 92 rollar block with a edlebrock top end kit with carb. So i'm not sure if they ment u will need a new harmonic balencer if ur engine is older or what.

you don't need to change the harmonic balancer...it stays..... what is needed is a c-r flex plate for a 50 oz motor..anyone has them a place in michigan called total performance specializes in such..you can order them from summit too.

I just done the swap. All you need is a 50oz flexplate. Depending on the trans you either need a 157 tooth flexplate or the 164 tooth which is identical to the aod trans flexplate.
